Very confused

I have super user on my phone, but the weird thing is that root checker says my phone isn't rooted :blink: I'm trying to wipe everything off the phone so I can totally reset it and start fresh (its a backup phone) so major deal but does anyone know how to fix this? I've tried flashing .sbf files but no avail..

Thanks for the quick response but I went to get my phone that was on my charger and it won't charge It keeps saying "Connect your charger" but I know this one is good because I used it for my Bionic.....ordering a new battery will fix this I guess
